Definitions

  • the present invention relates to improvements made to recoilless weapons, which can be fired from a partially confined and protected space, as well as to all weapons for which it is desired to limit the ergonomic effects of the environment due to noise, shock, toxicity or the "signature" of the propellants.
  • the invention overcomes these drawbacks.
  • a launching weapon without projectile recoil comprising a propellant gargousse, placed in a central position in a tube and interposed between on the one hand the projectile and on the other hand a ballast which provides compensation for the recoil pulse caused by launching the projectile.
  • the invention provides improvements to this type of weapon and it is characterized in that the ballast consists of a bundle of longitudinal wires, the plastic and aerodynamic characteristics of which are chosen so that their ejection provides only effects. rear limited.
  • the example treated relates more particularly to an individual anti-tank or anti-armored portable infantry weapon, without recoil, which can be fired from a partially confined space.
  • the invention also applies, without departing from its scope, whatever its vocation, launching projectiles, missiles or rockets, fired blow by blow or in burst, fired from the shoulder of a shooter or from a single or multiple mount, which can be mounted on a vehicle, ship or aircraft.
  • the weapon's launch tube 1, FIG. 1 is preferably made of composite material, based on glass fiber, aramid, carbon, etc., used either by filament winding, or by injection on a "braid", either by "pultrusion".
  • this tube 1 can also be made of metal, fabric, "sandwich” structure, or any other.
  • the launch tube 1 is equipped, in particular with a firing device 2, which is preferably either percussion, causing the ignition of the gargousse 4 by percussion of a primer 11, or with electric impulse, generating the ignition of the gargousse 4 by battery discharge in an igniter 11, directly or through a capacitor or a voltage booster.
  • a firing device 2 which is preferably either percussion, causing the ignition of the gargousse 4 by percussion of a primer 11, or with electric impulse, generating the ignition of the gargousse 4 by battery discharge in an igniter 11, directly or through a capacitor or a voltage booster.
  • this device can be of any other type (piezoelectric, optoelectronics, ...) without departing from the scope of the invention.
  • the launch tube 1 of the weapon contains the projectile 3, on the one hand and the divided ballast 5 on the other hand, said ballast 5 playing the role of a rear piston; the projectile 3 and the ballast 5, according to the invention, delimit the central combustion chamber 22 in which the gargousse 4 is housed.
  • the projectile 3 comprises the contactor warhead 6, the military charge 7, the safety rocket 8, the base of the rear body 9, the tail, preferably deployable, 10.
  • the base of the rear body 9 may be hollow, hence a better possible adjustment of the central combustion chamber 22 according to the invention, for the gargoyle 4, without knowing how to lengthen the launching tube 1, or reduce the stability (static margin) of the projectile .
  • the projectile 3 can also include any other equipment: detection or location sensor, propellant charge, guidance, trigger for subsequent operation, system for attack in overflight, etc.
  • the gargousse 4 comprises a primer or an igniter 11, the propellant 12 contained in a case 13 and a confinement according to the invention in compressible material 14 (for example, expanded materials or polyethylene, polyurethane, PVC foam, etc.) . It is this confinement which ensures, according to the invention, the pre-established evolution of the volume of the central chamber 22 of the gargousse 4; Without departing from the scope of the invention, the gargousse can be introduced into an external pocket 15, to complete this confinement.
  • compressible material 14 for example, expanded materials or polyethylene, polyurethane, PVC foam, etc.
  • the gargousse 4 can have another organization assuring it its original character of being of evolving volume.
  • the divided ballast 5 comprises according to the invention, a bundle of threads 16 (for example threads of polyamide, of polyethylene, etc.). These wires are assembled at the head 17, preferably by welding, gluing, inhibiting, tightening, etc.
  • the divided ballast 5 according to the invention may also comprise a sole made of flexible material 18 (produced for example by dipping or overmolding, in a polyurethane resin, silicone, etc.), with the aim of improving the rear sealing of the chamber combustion of said gargousse 4, after bursting of its confinement.
  • the propellant 12 is ignited and has produced gases, after the initiation of the primer or igniter 11.
  • the internal wall 19 of the compressible confinement 20 is then expanded, and said confinement 20 is compressed and resists the rise in internal pressure.
  • the device according to the invention makes it possible to delay in a pre-established manner the increase in pressure in the central chamber 22, the elevation and the expansion of the propellant particles in the central chamber, of variable volume, located between the projectile 3 and the ballast 5. In particular, it ensures better ignition of all of the propellant particles. This results in better system performance and better reproducibility of projectile ejection speeds.
  • the combustion of the propellant 12 contained in the gargousse 4 has generated gases which fill said central chamber 22 according to the invention; these gases propel the projectile 3 and the ballast 5 according to the law of variation of the quantities of movement.
  • the good axial strength of the wires 16 of the ballast 5 according to the invention allows a regular and axialized exit of said ballast.
  • ballast 5 also comes out of the tube, deploys and bursts under the aerodynamic effect.
  • the large lift of the ballast wires 16 according to the invention ensures, according to the invention, rapid braking and satisfactory radial dispersion.
  • the weapon according to the invention makes it possible to have weak effects on the environment, hence, in addition to compensating for recoil by the original and effective means of the wires 16 according to the invention: - little noise; - little smoke; - little toxic gas; - few mechanical rear effects.
